On my previous truck, Ram 2500 w/6.7 Cummins, I added Timbren elastomeric springs on the front to help with carrying the weight of my 8'2" Boss V plow. They worked, limiting front end drop when picking up the plow to less than an inch. The amazing thing is that they seemed to smooth out the ride even when the plow wasn't mounted...as they were in contact with the front axle all the time.
